About
I'm Vansh Mehta currently a backend engineer at Jio Platforms Limited.
I build backend systems from scratch and write walkthroughs of how each piece actually works. URL shorteners, rate limiters, key-value stores with WAL, LSM-tree compaction, Raft consensus, stream processors with watermarks, distributed caches — the boring-and-essential machinery underneath every product you use.
What you'll find here
Every post ships with:
- A working code repo on GitHub that you can clone and run
- A detailed walkthrough of how the code works, why I chose specific trade-offs, and what would change my mind
- An honest "what didn't work" section, because the dead ends teach as much as the working version
What you won't find here
- Catchy "Top 5" posts
- Theory without implementation (If theory has been uploaded then rest assured implementation is on its way)
- Tutorials that don't run
- Hot takes on framework drama
